Description
Technical field
This practicality is related to metal forming mold field, more specifically, it relates to it is a kind of have control drawing attenuated amount
Drawing punching die structure.
Background technology
Drawing is that plate blank is pressed into the hollow workpiece of various openings using cupping tool, or by Manufactured opening
Hollow object is processed into a kind of processing method for stamping of other shapes hollow object, and drawing is also named drawing；Punching is to lean on punching die pair
Plank applies pressure, and plank is determined to the forming and machining method in the hole of required shape and size.
In the prior art, in drawing process, uncertainty when due to flow of metal and in mould structure to plank
In the case that force is uneven, the case where peripheral wall of the product after drawing will produce local reduction, causes product thickness uneven, influence
Quality.
Utility model content
In view of the deficiencies of the prior art, this practical purpose is to provide a kind of drawing punching for having and controlling drawing attenuated amount
Mould structure has the design feature for preventing material thinned in drawing.
To achieve the above object, this practicality provides the following technical solutions：
A kind of have a drawing punching die structure for controlling drawing attenuated amount, including upper die holder, lower die holder, upper padding plate, under
Backing plate, upper clamp plate and lower clamp plate；The upper die holder is fixedly connected with the upper padding plate, and the upper padding plate is fixedly connected with the upper folder
Plate；The lower die holder is fixedly connected with the lower bolster, and the lower bolster is fixedly connected with the lower clamp plate；It is solid on the upper clamp plate
Surely it is connected with hollow plate, the hollow plate is fixedly connected with concave template, and Drawing Hole is provided on the concave template；Under described
The drawing punch-pin for stretching into the Drawing Hole is fixedly connected on clamping plate；The edge rounded corner of the Drawing Hole, the drawing punch-pin
The edge of upper surface is arranged in circular arc；Force transmitting board is provided with below the lower die holder, the force transmitting board abutting has mandril；Institute
It states and is fixedly connected with several on force transmitting board across the lower die holder, the lower bolster and the lower clamp plate, and along the drawing
The circumferentially uniformly distributed power transmission balancing pole of punch-pin；The upper end of the power transmission balancing pole, which abuts, holding pad, and the drawing punch-pin passes through institute
State holding pad；The holding pad is fixedly connected with the contour set for being arranged in the lower clamp plate, the lower bolster and the lower die holder
Component one；The gap block abutted with the concave template when being provided with molding on the holding pad.
So set, when molding, holding pad clamps tablet with concave template, with the movement of drawing punch-pin, metal tablet
It is drawn into Drawing Hole；The fillet of drawing punch-pin upper surface and the arc-shaped transitional surface at Drawing Hole edge reduce metal in stress
With the frictional resistance of concave template and drawing punch-pin contact surface when deformation, while concave template and drawing punch-pin are reduced in fillet position
On to metal tablet generate stress so that metal tablet can be flowed into more successfully in Drawing Hole, will not stress concentrate
And it is serious so that it is thinned around the corner；Make holding pad with cavity plate when clamping metal tablet around the power transmission balancing pole of setting,
The pressure applied on the surface thereof is uniform and stable；So that metal tablet stress balance in deformation, will not cause because of unbalance stress
All wall thickness so that local reduction is apparent；By adding gap block, between accurately controlling holding pad and concave template after molding
Away from preventing holding pad and concave template from clamping metal tablet and the mobility that hinders it in forming process；To realize in gold
Belong to drawing and forming process and ensures that its thickness change is not thinned uniformly.
Further setting：The punch being fixedly connected on the upper clamp plate in the Drawing Hole, in the drawing
Punching hole is offered on punch-pin.
So set, when drawing closes to an end, punch is moved downward with respect to drawing punch-pin, and work is punched out to metalwork
Industry；Drawing and punching two procedures are carried out at the same time to metal tablet to realize.
Further setting：The upper clamp plate, contour in the Drawing Hole is provided through on the upper padding plate
Component two is covered, the contour set component two is connected with the interior pushing block in the Drawing Hole；It slides and sets on the upper die holder
It is equipped with across the upper padding plate, the upper clamp plate and the hollow plate and the knockout rod that is abutted with the interior pushing block.
So set, in punching, interior pushing block first compresses metalwork with drawing punch-pin, to prevent in punch punching
Metalwork deforms, and improves punching quality；Contour set component two makes inner pushing plate that can return to original position after die sinking, to
Ensure the stability of its movement.
Further setting：The limit abutted against when being fixedly connected on the upper die holder and the lower die holder in molding
Column.
So set, by the way that limited post is arranged, the spacing of concave template and holding pad after molding is further limited, further
The mobility for preventing holding pad from clamping metal tablet with concave template and hindering it in forming process.
Further setting：Be fixedly connected on the lower die holder it is several be arranged in the lower bolster, the lower clamp plate and
Positioning pin on the holding pad offers the location hole for the positioning pin grafting on the concave template.
So set, positioning pin is inserted into location hole when molding so that each holding pad and concave template can accurate pairing, protect
The molding stress equalization for demonstrate,proving each metal tablet, to improve the stability of product.
Further setting：The inner guiding post for wearing the holding pad is fixedly connected on the lower clamp plate, in the cavity plate
The interior guide sleeve for the inner guiding post grafting is provided on plate.
So set, by adding inner guiding post and outer bush 30 so that in molding, the up-down structure of mold can be accurate
Cooperation to improve the kinematic accuracy of mold, and then improves the Forming Quality of product.
Further setting：It is interspersed with several pins one on the upper die holder, the upper padding plate and the upper clamp plate.
So set, passing through interspersed pin one so that deviation does not occur when mounted for upper die holder, upper padding plate and upper clamp plate,
Ensure the stability and kinematic accuracy of mould structure, and then improves the Forming Quality of product.
Further setting：It is interspersed with several pins two on the lower die holder, the lower bolster and the lower clamp plate.
So set, passing through interspersed pin two so that deviation does not occur when mounted for lower die holder, lower bolster and lower clamp plate,
Ensure the stability and kinematic accuracy of mould structure, and then improves the Forming Quality of product.
In conclusion this practicality has the advantages that：
1. metal tablet uniform force, resistance in drawing and forming is small；Effectively reduce the thinning phenomenon after drawing；
2. molding machine structure motion is precise and stable, be conducive to the stability for ensureing product quality in batch production.
